Answer:
-1/2
Step-by-step explanation:
In a linear relationship, the rate of change of one variable with respect to the other is <em>constant</em>. When we talk about <em>change</em>, we're looking for a <em>difference</em> of values.
If we look at the first and second rows, the change in x is 1 - (-1) = 2, while the change in y is 9 - 10 = -1. Usually we refer to these changes as Δx and Δy (read like "delta-x" and "delta-y"), and the <em>rate of change </em>is the number we get by dividing one of these by the other.
The rate of change we're used to seeing, sometimes called the <em>slope</em>, is Δy/Δx. So, using the values we've already found:

<u><em>Answer: m=2 and 2=m *The answer should be have positive sign.*</em></u>
Step-by-step explanation:
4m-7+10=15-2m ← Group like terms
add/subtract numbers
-7+10=3
4m+3=15-2m
subtract by 3 both sides of an equation.
4m+3-3=15-2m-3
simplify.
4m=-2m+12
add 2m both sides of an equation.
4m+2m=-2m+12+2m
simplify.
6m=12
divide by 6 both sides of an equation.
6m/6=12/6
simplify by equation.
12/6=2
6*2=12
2*6=12
12/2=6
m=2
Hope this helps!
Thanks!
Have a great day!
Answer:
True
Step-by-step explanation:
Simple random sampling chooses at random members of the population. This allows all members an equal probability of being selected for the sample.
